Further objects are yto provide an auto mobile'heater in which a floor plate or other type ot plate or heating surface may be employed of any desired shape, and which has a capacity for storing heat for a limited period, in which flexible or rigid conductors of any length are employed for directlyl ccnducting the heat from the exhaustsystem or o other hot portion ofthe apparatus to the lioor plate, and in which a heat switch* controlled from the interior of the car is provided or interrupting the flow of heat to the interior of the car.' f f 'A Further objects are to provide a very simple and easily produced type of'construction which necessitates only `a small hole in the ioor for its installation, and which is so made that it is reasily removed without loosening the connection `tothe exhaust system.

Embodiments of the invention are shown in the accompanying drawings in which:

Figure 1 is a plan view of the floor plate; Figure 2 isa sectional view through the floor plate and with'other parts in section, showing the yconnection employed; y

If desired, a screw Smay pass through the clip 6 and into the member 2 and a wingscrew 9v may pass through the clip and'intothe member et,v so` 65 4that thebmember: may be readily discen-k nected from the-"clip4 when it is desiredto remove the floor boards or otherwise alter f the arrangement.

In" operation,-the.heat is :transmitted by pipe `12'V vthrough the. clip r.11, xthrough the flexible conductorsf10, to-.itheblock or conductorI L1,-,through the switch 18, tothe block .or conductor 2 .and directly. to` .the oorj 'plate-or. radiatorf plate 1.

Infthe form shown in Figuresf to 7, the

same inventive idea isemployed. A floor.. plate 22'is .carried by.. the.removable v,floor Yboard 28 vand is provided with. a projecting portion 24 and., an'. opposed, projecting vportion 25,.. These portions are-connectedby a switch, not shown, similar-to the switch 18,

previously? described. They are .held to-1 .gether by means .of vtheplate 26f provided 'i with the' insulating-sheath27.which is identical in construction Lwith. that previously described. From .the.,portion 24, eithera single or a plurality of heat.,conductors28 extend forwardly and downwardly and terminate in a plug 29.. This. plug is slightly tapered and is adapted-to fit lwithin the recess 30 formed in a metal block attached tothe exhaust manifold 31. Thismetal block is provided with an extended portion .32

which is secured tothe exhaust manifold by.A means --of bolts 83. Obviously, other forms'. of construction could be employedfor themetal block and for attaching the rblockto the exhaust manifold.' Y y 'Itl is to be notedI that the conductor or conductors 28 have been shown as covered with an insulating sheath 34:. It vvis' to be dis,

tinctly understood that the block, and infact all `portions of the appara-tus, may becovered withl'insulation, as desired.

In this last`form ofthe invention, it is tojbenotedgthat the device is connected' to the .exhaust manifold merely by. positioning the 4floor i board; suflicient rigidity existing.v

in the conductor 28 to cause the insertion of the plug 29 in the aperture 30 when the device is being repositioned, wit-hout any attaching means such as screws or bolts. rlhe plug 29 is provided with a plurality of spring members 35 which, if desired, may be seated within the plug in small channels, as shown for instance in Figure 6, and which are adapted to frictionally bind against'the inner walls of the opening 30 in the metal block and thus maintain tight and secure contact for the plug.

This device is eminently suitedv lto the usual types of automobile constructions and may be as readily controlled as the device previously/described. It has the additional advantage iny that it permits the ready removal andinsertion of the floor board 23 without requiringA any bolt-s or nuts for attaching the plug tothe heating block carried` bythe .exhaust manifold. Instead the plug is properly positioned due to the rigidity of the conductor 28 which, although somewhat yielding, `nevertheless is suliiciently rigid to insure the correct insertion of the tapered plug 29- in the aperture 30 when the lloor board is .placed in its correct position.

Further, it is tobe noted that there is a very short length of conductor between the exhaust manifold and the heating plate and that this conductor directly conducts heat without requiring the circulation of gas, water, or other intermediate heat carrying mediums.

lt is to be noted particularly that the term floor plate or radiator plate is not intended to limit the* appara-tus to any particular position or shape of the radiator plate. rlhis radiator plate may be placed wherever desired in the car without in any way-departing from the spirit of this invention. Further than this, any type of in- ,sulation for any of the parts may be employedfi l It is valso to be noted that any metal may be employed for the several parts, preferably,I however, the metal employed is to have a high heat conductivity.

ltywill be seen,therefore, that a very simple form of automobile heater has been provided by -Vthis Ainvention which is easy to install, which is 1 highly eiiicient'in operation, and which vheats by a direct conduction olf-*heat from the exhaust system or other hot portion' of the automobile.

Although the invention yhas been described as primarilyl intended for use on automobiles, nevertheless it is to be distinctly understood that this invent-ion maybe .applied in other devices. For example, it isadapted to be used in aeroplane constructions for any type of plane.

Although the invention has been described .inl considerabledetail, such description is knation of a metallic radiator positioned within the body, a heat conductor providing a metal-to-metalconnection between the radiator and a portion of the exhaust system for the direct conduction of heat from the exhaust system to the radiator, and a movable member forming a portion of the connection between the radiator and the exhaust system and adapted to be moved to inheat conductor adapted for attachment to a portion of the exhaust system, said conductor having a low thermal resistance, and means for controlling the conduction of heat. i

In testimony that, we claim the yforegoing we have hereunto set our hands at Green Bay, in the county of Brown and state of Wisconsin. i
